Investigators are trying to figure out how a freight train jumped the track Tuesday night in the Florida Panhandle.
CSX Railroad officials say it happened about 9:30 p.m. on a section of track along Highway 90 between Chipley and Bonifay.
Seven cars derailed and six of them overturned.
The train was transporting crushed rock from Birmingham, Alabama to Sanford, Florida.
No hazardous materials were involved and there were no injuries.
